Malus

Purple Prince Crabapple Tree

Malus is a genus of about 30–55 species of small deciduous trees or shrubs in the family Rosaceae, including the domesticated apple (Malus domestica). The genus is native to the temperate zone of the Northern Hemisphere. The trees are commonly known as crabapples, crab apples, or wild apples.

Description

Malus species are generally small trees or shrubs, with a height of 4–12 meters at maturity. The leaves are 3–10 cm long, alternate, simple, with a serrated margin. The flowers are produced in spring, with five petals, white, pink, or red, and are often fragrant. The fruit is a pome, varying in size from 1–4 cm in diameter in most wild species, to 6 cm in Malus domestica.

Cultivation and Uses

Malus species are widely cultivated for their attractive growth habit, spring flower display, and decorative fruit. They are popular as ornamental trees in gardens and landscape design. The fruit of some species is edible, though generally too sour to be palatable when raw, and is used to make jelly, apple cider, and apple vinegar.

Crabapples are also used as rootstocks for domestic apples to add cold hardiness. The wood of Malus is used for making small items such as tool handles and is valued for its fine grain and attractive color.

Ecology

Malus species are important for wildlife, providing food for birds and mammals. The flowers are pollinated by insects, and the fruit is eaten by birds, which disperse the seeds.
